摘要
近年来,锂离子蓄电池得到了飞速发展和广泛应用。但是,锂离子蓄电池使用时的发热问题不仅会严重影响锂离子蓄电池的性能和寿命,而且存在安全隐患。因此提出利用有限元软件Ansys10.0对ICR65/400型锂离子蓄电池在其工作时温度场的分布情况进行仿真分析,并讨论了不同的放电速率和表面传热系数对锂离子蓄电池内部温度场分布的影响。结果显示,不同的放电电流和表面传热系数对电池内部温度的分布有着明显的影响。
Lithium battery was developed rapidly and applied widely. The performance and longevity of lithium battery were deeply influenced by the problem of heat generation, and the safety problems were appeared. By using the software Ansysl0.0, the temperature field equality for ICR65/400 Li-ion battery was analyzed and simulated, and the factors affecting the temperature lines with time and the temperature field of Li-ion battery including discharge rate and convection coefficient were discussed. The result indicates that the temperature field equality of ICR65/400 Li-ion battery is influenced obviously by the discharge rate and convection coefficient.
